To all whom 'it may concern:

4Be it knownfthat I, EDGAR P. WEBSTER, e. citizen of the United Statesof 'resident of Bridgeport, in the county ot Fairfield and State ciConnecticut, have invented certain nevi7 and useful Improve ments' inRoller-Bearings, ci which the ici lowing is e specification. v

The present invention reletes to improvements in roller bearings, andhas ior en ooject to provide a bearing of this type9 'which Wili operatein e more effective incliner, enti be so mounted as to beWeer-resisting, and in which friction Wili te reduced to e high de gree.Further objects ere the production ci? a roller bearing which Wili beinexpensive, and with which the process of menniecture will be greatlysirnpiiied anci feciiitsted. To this end, lf. propose to provide ebefitting in which the rollers will i'iorineilyl run prectically free,the cage merely acting` es e support and spacer therefor, and in whichtico Wear from usage vviil be teken up in o. man 11er as to not deterthe proper functioning of the bearing or reduce' the advantage thereof.I

vWith these and other objects in View, en embodiment of my invention issiiovvn in tile accompanying drawings, enti this einisocii ment Wiil `tehereinafter more iniiv de finally pointed out in the cieims.

'1.' A roller bearin comprising an annular one-piece cage v:ha ingspaced 1 openings formed thereln, rollers projectin through saidopenings, and trunnlons for ghe rollers projecting inwardly fromtheopposite edges k contact of the cage ,body with the'rollers.v i y 2. Aroller bearing comprising an annular one-piece cage having spaced oenings formed therein, rollers projecting t rough said openings, thebody wall of the cage having extensions on its oppositefedges inwardlybent in parallel relation to said wall and forming trunnions tooperatively engage the rollers at their endsand prevent frictionaleontact'of the cage wall with lsaid rollers.

3. A roller lbearing comprisin an annular one-niece cage having spaceopenings l presence of two said openings and formed with axiallyexltending recesses at their ends, the body vWall of the cage havingextensions on its opposite edges inwardly bent in' parallel relation tosaid wall, and engaged in said recesses to provide trunnions operatingto sustain the cage wall out of frictional contact with the rollers. y Y

4. A roller bearing comprising an annular one-piece ca e having spacedopenings formed therein, the body wall of the cage having integralextensions onits opposite sides extending inwardly to form` trunnions,adapted Ito engage axial recesses in rollers prrJlecting through saidopenings of the body wa i In testimony that I claim the foregoing as myinvention, I have signed my name in subscribing Witnesses.
